[Nut-upsuser] NUT Client Not Working, Server OK

[William Cole]

I hope that this is an appropriate post for this group.  Please let me know
if it should go elsewhere.

I am running NUT on RaspberryPi 3B+ [RPi] units using Buster.  The NUT
version is 2.7.4.

I have two UPS's in two different physical locations.  Each is attached to
its own RPi.
Both UPS's are APCs but of different models.

I have one APC attached to an RPi w/NUT configured as a server with the
following script entries:
---------------------------------





















*nut.confMODE=netserverups.conf[APCES850Server]     driver=usbhid-ups
 port=auto     desc=”APC ES850”     serial=4B2037P49872
 pollinterval=15     vendorid=051d[APCES750Client]     driver=usbhid-ups
 port=auto     desc=”APC ES750”     serial=3B0907X16989
 pollinterval=15     vendorid=051dupsmon.confMONITOR
APCES850Server at 192.168.1.100 <APCES850Server at 192.168.1.100> 1 upsmon
LASTPASS masterMONITOR APCES750Client at 192.168.1.101
<APCES750Client at 192.168.1.101> 1 upsremote LASTPASS slave*

Usual entries for upsd.conf and upsd.users.
-------------------------------
The other APC is attached to a different RPi w/NUT configured as a client
with the following script entries:
-------------------------------








*nut.confMODE=netclientups.conf[no entries]upsmon.confMONITOR
APCES850Server at 192.168.1.100 <APCES850Server at 192.168.1.100> 1 upsmon
LASTPASS masterMONITOR APCES750Client at 192.168.1.101
<APCES750Client at 192.168.1.101> 1 upsremote LASTPASS slave*
------------------------------
The server works fine.  The client will not connect, throwing a "UPS
APCES750Client at 192.168.1.101 is unavailable"error.

[Note that LASTPASS is just a placeholder for this note indicating the
password source.]
The passwords for upsmon and upsremote are the same.

I have this feeling that there is something that I am not understanding
about the server/client
relationship.

Suggestions would be very welcome.  Thank you so much.
